TCP Trunking

A TCP trunk is an IP tunnel under TCP control, capa ble of carrying packets from any number of user flows. By exploiting properties of TCP, a TCP trunk provides lastic and reliable transmission over a network, and autom atically shares the network fairly with other competing trun ks. Moreover, by aggregating user flows into a single t runk flow, TCP trunking can significantly reduce the num ber of flows that the network needs to manage, thereby all owing use of simplified management to achieve improved pe rformance. For example, when dealing with only a small number of TCP trunk flows, a router with a simple F IFO buffer can experience low packet loss rates.
